Thanks thanks! It helps a lot. I assume they are rounded heads on them screws. Any idea of the measurements? On something like this that actually changes the model, I'll do the changes in the CAD program then import back into Bryce. If not I'll just make a guess. ;-)

It is chrome now. I don't know how to make it more chromey than it is, unless I make it a mirror and change the blue diffuse and specularity to white. I wonder if I'm confusing "bridge" for something else. Here is a graphic I found off of google with terminology, useful to me since I never even touched a guitar before.
